This has definitely been posted before... I feel like StackOverflow isn't the right tool for this kind of info, either. Wasn't there some kind of website that sought to document all of the "checklist"-style information out there?
Stackoverflow is a wiki-style website. Anyone with enough rep can edit the accepted / top-voted answer.
Indeed, according to the stats it has been edited 71 times by 31 users, the biggest contribution from a single user is just 31% of the total. Seems pretty wiki to me.
